It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0033] See also Figures 1 to 8 An embodiment of the present invention provides a ventilation device for monitoring the environment of a refrigeration room. The ventilation device for monitoring the environment of a refrigeration room includes: an air inlet pipe 1, both ends of the air inlet pipe 1 are fixedly installed with mounting plates 11, and a plurality of air outlet pipes 2 are evenly installed on the mounting plates 11.

[0034] In the embodiments of the present invention, see Figures 1 to 6 , also includes:

[0035] The middle partition 3 is embedded in the middle part of the air inlet duct 1, and an air suction piece 4 for introducing external wind into the machine room is fixedly installed on the middle partition 3, and an air exhaust piece 5 is installed in several of the air outlet ducts 2. The air suction piece 4 is transmission-connected with the air exhaust piece 5. Ventilation holes 301 are evenly opened on the middle partition 3, and a blocking piece 6 for sealing the ventilation holes 301 is installed on the middle partition 3. An air inlet elbow 12 is installed at one end of the air inlet duct 1, and a blocking piece 2 7 for sealing several air outlet ducts 2 is installed on the air inlet elbow 12. A detection component 14 is installed in the air inlet elbow 12, and an air outlet elbow 13 is installed at the other end of the air inlet duct 1. A detection component 2 15 is provided above the air outlet elbow 13;

[0036] The intermediate pipe 9 is embedded in the middle of the air inlet pipe 1 and located outside the middle partition 3 , and one end of the intermediate pipe 9 facing away from the air inlet pipe 1 is connected to the refrigerator 91 .

[0037] Among them, the air suction member 4 includes a power motor 41 fixedly mounted on the middle partition 3, and the output end of the power motor 41 is fixedly sleeved with a multi-stage fan blade 42, and the output end of the power motor 41 is also coaxially fixedly connected with a transmission rod 43, and the end of the transmission rod 43 away from the power motor 41 passes through the air outlet bend 13, and is installed with a composite pulley 44 for transmission connection with the exhaust members 5 on several air outlet pipes 2, and the exhaust member 5 includes a rotating rod 51, and the rotating rod 51 is rotatably mounted on the air outlet pipe 2, and the end of the rotating rod 51 extending into the air outlet pipe 2 is fixedly mounted with a fan blade 52, and the other end of the rotating rod 51 is fixedly sleeved with a pulley 53, and the pulley 53 is connected to the composite pulley 44 through a belt drive.

[0038] It should be noted that: when in use, the air inlet pipe 1 is installed at a high place in the refrigeration room, and the air outlet elbow 13 is extended into the interior of the refrigeration room. When ventilation is in progress, the power motor 41 of the air suction member 4 is started to drive the multi-stage fan blades 42 to suck in the cold air from the outside through the air inlet elbow 12 and introduce it into the refrigeration room from the air outlet elbow 13. When guiding the air, the power motor 41 synchronously drives the transmission rod 43 to rotate. The transmission rod 43 is connected to the pulley 53 through the composite pulley 44 through the belt drive, driving the rotating rod 51 to rotate, thereby driving the fan blades 52 to rotate, and the cold air in the refrigeration room High-temperature gas is discharged from the air outlet pipe 2, thereby realizing simultaneous suction and exhaust. Such an integrated device makes the installation of the ventilation device more convenient and integrates suction and exhaust, thereby improving ventilation efficiency. Furthermore, during ventilation, the detection component 1 14 and the detection component 2 15 are used to monitor the indoor and outdoor environment of the refrigeration room, and the refrigerator 91 is used to further cool the introduced gas to improve the heat dissipation effect. When the sealing component 1 6 and the sealing component 2 7 are used to detect environmental abnormalities, the air inlet pipe 1 and the air outlet pipe 2 can be closed in time, thereby realizing the control of the ventilation device.

[0039] Furthermore, the detection component 14 includes a temperature and humidity sensor and a dust sensor arranged in the air inlet elbow 12, and the detection component 2 15 includes a temperature and humidity sensor, a refrigerant monitoring sensor and a dust sensor arranged on the mounting plate 11 on one side of the air outlet elbow 13. It is worth noting that when the sensors of the detection component 14 and the detection component 2 15 are used to detect the air environment of the refrigeration room, when refrigerant leakage is found, a timely warning is given, so that the ventilation device is closed by using the blocking component 1 6 and the blocking component 2 7.

[0040] In the embodiments of the present invention, see Figure 1 、 Figure 4 、 Figure 5 and Figure 6The blocking member 6 includes two groups of electric rods 61, which are symmetrically distributed based on the axis of the middle partition 3. The telescopic ends of the two groups of electric rods 61 are fixedly mounted with a connecting bracket 62, and the connecting bracket 62 is mounted with a blocking block 63 for sealing the plurality of ventilation holes 301;

[0041] It should be noted that when the blocking member 6 is in use, during normal ventilation, the electric rod 61 is controlled to extend, so that the blocking block 63 is away from the ventilation hole 301. When the air inlet pipe 1 needs to be closed, the electric rod 61 is controlled to retract, driving the blocking block 63 to be inserted into the ventilation hole 301, sealing the ventilation hole 301, and completing the blocking of the air inlet pipe 1.

[0042] In the embodiments of the present invention, see Figure 1 、 Figure 4 、 Figure 5 and Figure 6 The second blocking member 7 includes a mounting ring 71, which is rotatably mounted on the air outlet elbow 13. A windshield 72 for blocking a plurality of air outlet pipes 2 is mounted on the outer edge of the mounting ring 71, and an outer gear ring 73 is mounted on the mounting ring 71. A servo motor 74 is mounted on the mounting plate 11 near the air outlet elbow 13. A transmission gear 75 is fixedly sleeved on the output end of the servo motor 74, and the transmission gear 75 is meshed with the outer gear ring 73.

[0043] It should be noted that when the sealing member 7 is in use and the air outlet duct 2 needs to be closed, the servo motor 74 is started to drive the transmission gear 75 to rotate, and the transmission gear 75 engages with the outer ring gear 73, thereby driving the outer ring gear 73 to drive the mounting ring 71 to rotate until the wind shield 72 is rotated to block and seal the air outlet duct 2. When opening, the wind shield 72 is driven away from the air outlet duct 2.

[0044] In the embodiments of the present invention, see Figure 1 、 Figure 2 、 Figure 3 and Figure 8 The end of the air outlet bend 13 facing away from the air inlet 1 is equipped with a telescopic bellows 8, and the end of the telescopic bellows 8 is equipped with an air guide cover 81. The air guide cover 81 is evenly provided with a plurality of air guide holes 801. A hydraulic rod 82 is fixed to the outer wall of the air outlet bend 13, and the output end of the hydraulic rod 82 is fixedly connected to the air guide cover 81.

[0045] It should be noted that when the air outlet bend 13 is in use, the hydraulic rod 82 drives the air guide cover 81 to move up and down, thereby adjusting the position height of the air guide cover 81. When guiding air, the position of the air guide hole 801 is adjusted to facilitate rapid ventilation and heat dissipation of local high-temperature locations.

[0046] In the embodiments of the present invention, see Figure 1 、 Figure 2 、 Figure 3 and Figure 7 The air inlet duct of the refrigerator 91 is connected to the air inlet elbow 12. The bottom end of the air inlet elbow 12 is threadedly mounted with an adapter ring 16, and a honeycomb activated carbon filter cake column 17 is embedded in the adapter ring 16;

[0047] It should be noted that: in this way, during ventilation, the air inlet pipe 1 uses the refrigerant 91 to further cool the introduced gas, thereby improving the ventilation and heat dissipation effect, and uses the honeycomb-shaped activated carbon filter cake column 17 to filter during ventilation, thereby improving the cleanliness of the introduced air, and the adapter ring 16 is threadedly connected to the air inlet elbow 12, which facilitates the later disassembly and replacement of the activated carbon filter cake column 17;

[0048] In this embodiment, the bottom end of the adapter ring 16 is connected to an electrostatic dust removal box 18. When the air is guided, the electrostatic dust removal box 18 is used to efficiently remove dust from the air sucked into the air inlet elbow 12, thereby preventing dust from entering the refrigeration room and affecting the operation of the equipment in the room.

[0049] The working principle of the ventilation device for refrigeration room environment monitoring provided by the present invention is as follows:

[0050] When in use, install the air inlet pipe 1 at a high place in the refrigeration room, and extend the air outlet elbow 13 into the interior of the refrigeration room. When ventilation is in progress, start the power motor 41 of the air suction member 4 to drive the multi-stage fan blades 42 to suck in the cold air from the outside through the air inlet elbow 12, and introduce it into the refrigeration room from the air outlet elbow 13. When guiding the air, the power motor 41 synchronously drives the transmission rod 43 to rotate. The transmission rod 43 is connected to the pulley 53 through a belt drive using a composite pulley 44, driving the rotating rod 51 to rotate, thereby driving the fan blades 52 to rotate, and the high-temperature gas in the refrigeration room The air is discharged from the air outlet pipe 2, thereby achieving simultaneous suction and exhaust. Such an integrated device makes the installation of the ventilation device more convenient and integrates suction and exhaust, thereby improving ventilation efficiency. Furthermore, during ventilation, the detection component 1 14 and the detection component 2 15 are used to monitor the indoor and outdoor environments of the refrigeration room, and the refrigerator 91 is used to further cool the introduced gas to improve the heat dissipation effect. When the blocking component 1 6 and the blocking component 2 7 detect an abnormal environment, the air inlet pipe 1 and the air outlet pipe 2 can be closed in time, thereby achieving control over the ventilation device.

[0051] Specifically, when the blocking member 1 6 is in use, during normal ventilation, the electric rod 61 is controlled to extend, thereby moving the blocking block 63 away from the ventilation hole 301. When the air inlet duct 1 needs to be closed, the electric rod 61 is controlled to retract, driving the blocking block 63 to be inserted into the ventilation hole 301, sealing the ventilation hole 301 and completing the blocking of the air inlet duct 1. When the blocking member 2 7 is in use, when the air outlet duct 2 needs to be closed, the servo motor 74 is started to drive the transmission gear 75 to rotate. The transmission gear 75 engages with the outer ring gear 73, thereby driving the outer ring gear 73 to drive the mounting ring 71 to rotate until the wind shield 72 is driven to block and seal the air outlet duct 2. When opening, the wind shield 72 is driven away from the air outlet duct 2, thereby achieving ventilation control of the ventilation device.

[0052] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
